Chocolate Cake with Nutella Icing

**Cake:**

1. Preheat the oven to 350°F. Grease and flour three 8″ or 9″ round cake pans.
2. In a large bowl, whisk together the sugar, flour, cocoa powder, baking soda, baking powder, and salt until evenly combined.
3. Add the vanilla, eggs, buttermilk, and oil. Stir until combined.
4. Stir in the hot coffee quickly to ensure it’s evenly distributed. The batter will be very thin.
5. Pour the batter into the prepared cake pans. Bake for 30-40 minutes, or until a toothpick comes out clean.
6. Let the cakes cool completely.

**Nutella Icing:**

1. In a large mixing bowl or stand mixer, cream together the softened butter and Nutella until well combined (about 3 minutes).
2. Add the salt, vanilla bean paste, and powdered sugar. Mix on low until combined; it will be clumpy.
3. Add the heavy cream and mix on low until combined, then increase the speed to medium-high and beat until fluffy (about 3 more minutes).
4. Ice the cooled cakes with the Nutella icing.
